Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application 1] The present invention relates to a safety belt used to prevent workers from falling during work at high places such as construction sites.

[Prior art 1] Conventionally, this type of safety belt consists of a waist-fastening belt that is worn by wrapping around the body's torso, a D-ring through which the waist-fastening belt is inserted, and a proximal end formed by weaving or the like into the ring. It consists of a tied rope and a hook attached to the tip of the rope, and is used by hooking the hook to a structure or other attachment equipment.

However, in the above conventional safety belt, the rope gets in the way when not in use, making it difficult to deal with it.

For this reason, it is common practice for contractors to hang the rope over their shoulders to prevent it from interfering with the work as much as possible.

However, this is dangerous because there is a risk that the rope may get caught in surrounding structures, etc., and a means for safely and compactly storing the rope has been required.

In order to meet the above requirements, in recent years, safety belts have been used instead of ropes, and when the belts are not in use, they are wrapped around the take-up reel attached to the waist belt so that they do not get in the way of work. is 1#! It is being emitted.

[Problem to be solved by the invention] However, the above-mentioned safety belt equipped with a narrow belt does not use conventional ropes, D-rings, etc. that comply with the strict structural standards, and therefore has not been approved for exemption. There are other problems, such as the need to receive special approval, and the structure of the take-up reel and the like to be complicated and expensive.

The present invention was made to solve the problems mentioned above, and its purpose is to allow conventional ropes, dolls, etc. that conform to structural standards to be used in their original shape. Not only is there no need to worry about structural strength, but
To provide an inexpensive safety belt that can be pulled out and retracted smoothly and reliably.

[Means for Solving the Problems] The safety belt of the present invention includes: a body tightening belt that is worn around the torso of the body; a rotating D ring attached to the belt;
A nine-part part rotatably attached to the rotary ring, a take-up reel integrally attached to the round part, a mainspring that biases the take-up reel in the 8 winding direction, and the above-mentioned circle 111j.
a loaf whose proximal end is attached to the rope and which is wound around the take-up reel; a hook attached to the tip of the rope; and the rope is temporarily locked against the winding force of the take-up reel. The present invention is characterized in that the winding reel is a cap-shaped reel that winds the rope in a spiral shape.

[Embodiment 1] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a body tightening belt, which is provided with a buckle 2 at one end, and is adapted to be worn by being wrapped around the torso of the worker.

A rotating pongee winder A as described below is attached to the body tightening belt 1.

FIG. 2 shows a cross section of the rotating ring pongee winder A, and 3 is the rotating ring main body. The body tightening belt 1 is inserted inside the rotating ring main body 3, and the rotating ring main body 3 is attached to the waist tightening belt 1 so that it will never come off.

A nine-piece portion 4 is rotatably attached to the outer central portion of the rotary ring body 3.

Reference numeral 5 denotes a mainspring case, which is fixed to the rotating ring main body 3 via a mounting piece 5a. The mainspring case 5
Mainspring 6 is stored inside, and fIII is stored outside.
The L end portion is fixed to the mainspring case 5.

Reference numeral 7 denotes a take-up reel, the central part of which is fixed in a state where it fits into the round eye part 4, and rotates together with the nine-part part 4. The inner end of the mainspring 6 is fixed to the take-up reel 7, and urges the take-up reel 7 and the V-circle part 4 in the winding direction.

The rope 8 is stored in a wound state in the outer circumference winding WIT a of the winding reel 7. The inner end 8a of the rope 8 is tied to the circle I section 4 by, for example, a satsuma layer.

Reference numeral 9 denotes a cover, which is fixed to the rotating ring main body 3. A pull-out hole 9a is formed at an appropriate position on the side surface of the cover 9, and the rope 8 wound around the outer peripheral winding groove 7a is pulled out.

As shown in FIG. 1, a rope stopper 10 is attached to the body tightening belt 1 near the drawer part of the row 18, and the rope stopper 10 temporarily locks the row 18 against the winding force of the mainspring 6. , the row 18 can be pulled out by the required length. 10a is a lock release lever. The means for temporarily locking the rope 8 is not limited to the rope stopper 10 described above, and any mechanism that can temporarily lock the rope 8 against the winding force of the mainspring 6 may be used. Further, this locking mechanism may be provided near the pull-out hole 9a of the cover 9 or on the take-up reel 7 or the like.

” 7 hooks 11 are attached to the tip of the rope 8.

Since the safety belt of this embodiment is constructed as described above, when using it, after wrapping the body tightening belt 1 around the torso of the body and wearing it, the rope 8 is pulled against the winding force of the mainspring 6. When the rope 8 is pulled out from the take-up reel 7 and loosened after being pulled out to an appropriate degree, the rope stopper 10 works to lock the rope 8 from being wound up. In this state, work is carried out by hanging the seven hooks 11 at the tip of the rope 8 onto a structure or a master rope attached to the structure.

When not in use, remove the 7-piece hook 11 from the main rope, etc., and release the lock of the rope stopper 10 using the lock release lever 10a.The rope 18 is wound onto the take-up reel 7 by the winding force of the mainspring 6, and rotates. It is stored in the ring winder A. In this case, the 7γ ribbon 11 may be placed in an appropriate storage bag (not shown) provided on the body tightening belt 1.

Figure Pt53 and Figure 4 show another embodiment of the invention.

The body tightening belt 1, rotating ring main body 3, round part 4, mainspring case 5, mainspring 6, rope 8, etc. in the safety belt of this embodiment are the same as the corresponding members of the first embodiment shown in FIG. It has almost the same remains and functions.

In FIG. 3, reference numeral 12 denotes a take-up reel, which has a hat-like shape as a whole, and is adapted to wind the rope 8 in a spiral shape on its outer surface.

13 is a cover, on the side of which is a drawer opening 1 for the rope 8.
3a is formed.

14 is a rope stopper, as shown in FIG. 5, which temporarily holds the rope 8 by sandwiching it between the rubber play (14a) and the pickpocket (7) 14b.

Incidentally, as shown in FIG. 6, a spiral winding groove 12& may be formed on the winding reel 12.

[Effects of the invention] (1) Since the rope is wound into and pulled out from the take-up reel that is integrally attached to the round part of the rotating ring, the rotating rings and ropes, etc. in the United States can be used as they are or can be significantly modified. 6 (2) The take-up reel is biased in the winding direction to automatically wind the rope, and there is no need to worry about structural strength.
The rope that has been pulled out can be temporarily locked between the slits and pulled out as needed, making it easy to operate and work.

(3) Since the take-up reel is formed into a cap shape to wind the rope in a spiral shape in a compact manner, the rotating ring 8 taker can be made smaller.
